I read on hear, quite a few people recommending Valvoline Restore & Protect engine oil. With it just coming out, do you have any significant evidence of the claims it makes?
I have read on other forums where it has quieted noisy engines, looking through the valve cover is cleaner, another one is where they used a bore scope on a Toyota engine..
Curious if any of you all seen any evidence..
Thanks..
